Step 1: Case

i needed something cylindrical and after experimenting around i decided on 3 basic criteria: 
1 again, it had to be cylindrical.
2 it had to be re-close able.
3 it had to be lying around the house somewhere.
a film canister was close but just a little bit too small, and i finally decided on an empty pill bottle.

Step 2: The stuff

you need a case
9v battery
some wire
9v adapter thing...
old pcb or strip board. 
10k ohm resistor (i salvaged mine from another old pcb)
switch
leds

Step 3: A clean work surface...

ya even i will admit its a bit of a mess...

Step 4: Circutry

its more difficult but you can use an old piece of PCB if its free of copper coating, and yes strip board does work better

Step 5: Schematic

very basic, shouldn't be too hard to follow...

Step 6: LED's

the one i showed in the parts picture i use all the time and i wasn't sure i wanted to give it up, and then i found a few old laser pointer things that had a little light on them, i saved these, the battery's where dead so my teacher was throwing them away!

Step 7: Soldering

i made my own holder thing and it works quite well, i don't always use the tweasers though

Step 8: Drill and fit...

i used a 1/2 inch drill bit to make a hole, and then cleaned it up with  a razor blade.

Step 9: Hot glue

before you commit to anything solder the wire leads to the battery clip,then hot glue the circuit board in

for some strange reason girls like to do there hair, even more of a mystery is why they do it in the boys bathroom, granted there's a bigger mirror but still...
those little hair band thingy's make great high durability rubber bands.
apparently they all have specific names for there's sizes! i don't think i will ever understand women
